Hands-On Kubernetes on Azure - Second Edition

Overview of this book

From managing versioning efficiently to improving security and portability, technologies such as Kubernetes and Docker have greatly helped cloud deployments and application development. Starting with an introduction to Docker, Kubernetes, and Azure Kubernetes Service (AKS), this book will guide you through deploying an AKS cluster in different ways. You’ll then explore the Azure portal by deploying a sample guestbook application on AKS and installing complex Kubernetes apps using Helm. With the help of real-world examples, you'll also get to grips with scaling your application and cluster. As you advance, you'll understand how to overcome common challenges in AKS and secure your application with HTTPS and Azure AD (Active Directory). Finally, you’ll explore serverless functions such as HTTP triggered Azure functions and queue triggered functions. By the end of this Kubernetes book, you’ll be well-versed with the fundamentals of Azure Kubernetes Service and be able to deploy containerized workloads on Microsoft Azure with minimal management overhead.

Setting up prerequisites

In this section, we will set up the prerequisites we need in order to build and run functions. We need a container registry and a development machine.

We introduced container images and a container registry in Chapter 1, Introduction to Docker and Kubernetes, in the section on Docker images. A container image contains all the software required to start an actual running container. In this chapter, we will build custom Docker images that contain our functions. We need a place to store these images so that Kubernetes can pull these images and run the containers at scale. We will use the Azure Container Registry for this. Azure Container Registry is a private container registry that is fully managed by Azure.

Up to now in this book, we have run all the examples on the Azure Cloud Shell. For the example in this chapter, we need a separate development machine because the Azure Cloud Shell doesn't allow you to build Docker images. We will create a new...
